1) Remove the dead code with 'eraseDeadCode', not with 'eraseTokens' because of the possible presence of labels.
2) It's impossible that in tokenizer there is pattern like 'if (true|false) {code;} else if (cond) {code_cond;}' because the function 'Tokenizer::elseif' adds '{' between 'else' and 'if', hence a code path is redundant, so it's removed from code.

About
The original name of this program is "C++check" but it was later changed to "cppcheck".
Manual
A manual is available online:

Compiling
Any C++ compiler should work.
To build the GUI, you need Qt.
When building the command line tool, PCRE is normally used.
PCRE is optional.
There are multiple compilation choices:
* qmake - cross platform build tool
* Windows: Visual Studio
* Windows: Qt Creator + mingw
* gnu make
* g++
qmake
=====
You can use the gui/gui.pro file to build the GUI.
cd gui
qmake
make
Visual Studio
=============
Use the cppcheck.sln file. The rules are normally enabled.
To compile with rules (pcre dependency):
* the pcre dll is needed. it can be downloaded from:
http://cppcheck.sf.net/pcre-8.10-vs.zip
To compile without rules (no dependencies):
* remove the preprocessor define HAVE_RULES from the project
* remove the pcre.lib from the project
Qt Creator + mingw
==================
The PCRE dll is needed to build the CLI. It can be downloaded here:
http://software-download.name/pcre-library-windows/
gnu make
========
To build Cppcheck with rules (pcre dependency):
make HAVE_RULES=yes
To build Cppcheck without rules (no dependencies):
make
g++ (for experts)
=================
If you just want to build Cppcheck without dependencies then you can use this command:
g++ -o cppcheck -Ilib cli/*.cpp lib/*.cpp
If you want to use --rule and --rule-file then dependencies are needed:
g++ -o cppcheck -lpcre -DHAVE_RULES -Ilib -Iexternals cli/*.cpp lib/*.cpp externals/tinyxml/*.cpp
mingw
=====
make LDFLAGS=-lshlwapi
Cross compiling Win32 (CLI) version of Cppcheck in Linux
sudo apt-get install mingw32
make CXX=i586-mingw32msvc-g++ LDFLAGS="-lshlwapi"
mv cppcheck cppcheck.exe
